Mariwin Roberts Bio
May 24, 1948 - August 4, 2017 / Gemini / Age 69
Mariwin Roberts was an American-born Penthouse model, nude model, and porn actress, born Michelle Roberts on May 24, 1948 in Fort Worth, Texas, United States.
Throughout her modeling career, she has also appeared as Jill Stonegate.
Mariwin Roberts was crowned Penthouse Pet of the Month in April 1978, stepping into the spotlight at 29 years old. With her statuesque 36-23-35 figure, soulful hazel eyes, rich brown hair, and enhanced breasts, Mariwin expresses confident glamour — elegant, expressive, and fully in command of allure.
Mariwin Roberts entered Penthouse with the kind of presence that feels both California-bright and just a little bit dangerous. There was something wonderfully seventies about her appeal — relaxed on the surface, but edged with the kind of knowing confidence that made drive-in fantasies and late-night screens feel more alive. She did not come across as overconstructed or remote. Instead, she gave the impression of a woman who understood exactly how to hold attention while keeping a little of herself just beyond reach.
What made Mariwin especially memorable was the contrast in her image. She moved through erotic and exploitation cinema, certainly, but there was more to her than the easy assumptions that world invites. Beneath the glamour was a woman with a real creative life of her own: educated, artistically inclined, and working as an advertising assistant while building a screen presence in parallel. That balance gave her a different sort of appeal. She felt less like a one-note fantasy and more like a woman with several identities moving at once, each sharpening the others.
That complexity gave her April 1978 Penthouse appearance its particular interest. Mariwin Roberts had graduated from Fillmore High School in California in 1966 and later completed her studies at Santa Barbara City College in 1974, bringing an unusually grounded and deliberate trajectory to the page. Between 1976 and 1978, she acted in adult films and also appeared in a handful of lowbrow seventies drive-in exploitation comedies, embracing a corner of cinema that thrived on boldness, speed, and sheer nerve. Penthouse recognized that charge and made her Pet of the Month in April 1978. The association deepened further when she went on to star in the hardcore feature Pet of the Month: Mariwin Roberts that same year, a title that turned her Penthouse identity into something more fully cinematic.
What lingers about Mariwin Roberts is precisely that mix of glamour and authorship, performance and personality. She was not simply passing through a provocative era; she was part of its texture, bringing intelligence and artistic instinct into places that often left little room for either. She died in 2017 in Camarillo, California, at the age of sixty-nine, but the image that remains is very much alive: a woman of warmth, nerve, and creative appetite, who gave Penthouse a distinctly Californian kind of allure.
